7 Claims.

My invention relates to improvements in window burglar guard and alarm.

One of the objects of my invention is to provide a novel guard for a window which will deter the entrance of a burglar through a window, and which upon being disassembled to enable his ingress through the window, will make a clatter that will alarm the burglar and will attract the attention or" people in the house or nearby.

A further object of my invention, is to provide a device of the kind which is simple, cheap, strong, durable, not likely to get out of order, is efficient in its operation, and which may be easily and quickly applied to windows of different dimensions.

The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawing, which illustrates the preferred embodiment of my invention,

Fig. 1 is an outside elevation, partly broken away, showing my improved burglar guard and alarm applied to a window frame.

Fig. 2 is a horizontal section on the line 2--2- of Fig. 1.

Fig. 3 is an enlarged view of a central portion of the guard and alarm shown partly in elevation and partly in vertical section.

Fig. 4 is an enlarged longitudinal sectional View of one of the bar holding sleeves.

Similar characters of reference designate similar parts in the different views.

1 designates the stiles of a window frame, 2 the sill thereof, 3 the upper sash and 4 the lower sash.

Below and in the vertical plane of the upper sash 3, and between the stiles 1 are two alined inclined bars 5' and 6.

For holding alined the bars 5 andfi, which, as shown, may be tubular, a connecting means comprising a sleeve '7 is provided. The sleeve 7 is slidable on the upper bar 5 onto and off from the lower bar 6. To limit the movement of the sleeve '7 there is mounted in a threaded hole in the bar 5 a removable screw 3 which extends through a longitudinal slot 9 in the sleeve 7, the slot being long enough to permit the sleeve 7 being slid upwardly on the bar 5 to a position in which the sleeve will disengage from the bar 6.

The sleeve '7 at its middle portion is provided with two screw threaded arms 10 and 11, which, as shown, aline with each other, extend in opposite directions from the sleeve '7, are in the same vertical plane as the bars 5 and 6, and are inclined to the axis of said bars and of the sleeve '7.

A second pair of bars 12 and. 13 are respectively alined with the arms 10 and 11.

FFEC

Two sleeves 14 and 15 are respectively slidable on the bars 12 and 13 into and out of engagement with the threaded arms 10 and 11.

The lower end of the sleeve 14 is threaded so as to be adapted to be screwed into holding engagement with the upper arm 10.

The

upper end of the sleeve 15 is internally threaded so as to have holding engagement with the lower arm 11.

- The outer ends of the bars 5, 6, 12 and 13, that is the ends of said bars which are distant from the sleeve '7 are fastened to the window frame, so

that when their inner ends, or

ends which are adjacent to the sleeve 7 are disengaged from the parts with which said inner ends engage, the bars will swing downwardly by gravity, and will strike the window frame, thus making a noise which will startle the burglar and which will attract the attention of the occupants of the house or persons nearby.

For so fastening the bars 5, 6,

12 and 13 to the members 18.

The members 18 which are attached to the bars 5 and 6 are respectively fastened to one of the stiles 1, just below the upper sash 3, and to the sill 2 adjacent to the opposite stile 1.

The member 13 which is pivotally connected with the upper end of the bar 12 is attached to the last named stile, just below the upper sash 3. The member 18 which is attached to the member 16 on the lower end of the bar 13 is fastened to the sill 2 near the adjacent stile 1.

The parts having been assembled as described, ingress of a burglar through the window below the upper sash will be prevented by the guard. In case he unscrews either of the sleeves 14 or 15 from the arms 10 or 11, the bar 12 or 13 which is thus detached from the adjacent arm 10 or 11, will swing by gravity downwardly. If it be the bar 12 which is released, it will strike the adjacent stile 1 and thus will make a noise, and the sleeve 14 will slide from the bar 12 and will fall upon the sill, thus adding to the clatter.

When the bar downwardly against the sill 2.

The bar 5 when released will swing with the sleeve 7 against the adjacent stile 1, thereby making more noise and adding to the alarm of the burglar and further tending to awaken the household.

The guard and alarm device is disposed at the outer side of the lower sash 4, so will not interfere with the free raising and lowering thereof from the inside. The upper fastening members 18 will prevent the burglar from lowering the upper sash without removing said members and disassembling the guard structure.

Such disassembling, as has been explained, will make a noise that will alarm the burglar and attract attention of others. This is usually sufiicient to cause the burglar to discontinue his efforts at getting through the window, or trying to enter the house.

Many modifications of my invention, within the scope of the appended claims, may be made without departing from the spirit of my invention.

What I claim is:

1. In a window burglar guard and alarm, the combination with a window frame, of a pair of alined inclined bars extending transversely between opposite stiles of said frame, a sleeve telescopically engaging adjacent end portions of said bars and movable off from one of said bars and having two inclined arm-s extending in opposite directions therefrom at an angle to the axis thereof, a second pair of bars respectively alined with said arms, two sleeves respectively movable on said last named bars into and out of holding engagement with said arms, and means so pivoting on horizontal axes the distant ends of the bars of each pair to opposite side portions of said frame, that the bars, when released at their adjacent ends, will swing by gravity against said frame and thus sound an alarm.

2. In a window burglar guard and alarm, the combination with a window frame, of a pair of alined inclined bars extending transversely between opposite stiles of said frame, a sleeve telescopically engaging adjacent end portions of said bars and movable off from one of said bars and having two inclined threaded arms extending in opposite directions therefrom at an angle to the axis thereof, the lower of said arms being threaded, a second pair of bars respectively alined with said arms, two threaded connecting members respectively movable on said last named bars into and out of holding threaded engagement with said arms, and means so pivoting on horizontal axes the distant ends of the bars of each pair to opposite side portions of said frame, that the bars, when released at their adjacent ends, will swing by gravity against said frame and thus sound an alarm.

3.
